When the drum is under high-speed operation, the suspension enters the drum through the feeding pipe. Under the action of centrifugal force, the suspension is evenly distributed in the filter cloth of the drum. The liquid phase passes through the pore of filter cloth, the gap of screen mesh, and the filter hole of the drum and then is discharged from the outlet of the mother liquid pipe; while the solid phase is intercepted to form a ring filter slag layer on the filter mesh. When discharging, the main engine of inverting centrifuge first slows down to the discharging speed, then starts the discharging motor and pushes the pusher out of the drum. Because the two ends of the filter cloth turn over, and the retained material is turned to the outside of the filter cloth.

Feeding, separating, washing, dehydration, and other operating procedures are completed under full speed; discharging is completed under the condition of deceleration, which avoids material contact with subject other than equipment, and can protect the operator and material from pollution as well.
